Which agricultural consequence stemmed mainly from terraces built without sufficient drainage in pre-Incan South America?

💡 Explanation

Localized anaerobic soil conditions arose frequently, because waterlogged terraces experienced slowed decomposition. This caused buildup of organic matter and inhibits enzymatic activity in the soil rather than runoff or salinization; therefore plants can't survive.
